1) Open up register-styles.php located in the folder broadscopeincludes and replace:

'elements' => '.cufon_headings',

with:

'elements' => '.cufon_headings, .avia_mega',

2) Because of the slider structure it’s not easily possible to integrate self hosted videos. The new theme Brightbox uses a different slider slider structure which allows to embed videos. But on the other hand it doesn’t support a fullwidth slideshow like Broadscope.
